CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a U.S. National Stage Application filed under
35 U.S.C. .sctn. 371 of International Application No.
PCT/EP2016/060857, filed May 13, 2016, which claims the benefit of
European Application No. EP15172166.9, filed Jun. 15, 2015. Both of
these applications are hereby incorporated by reference in their
entireties.
DESCRIPTION
The invention relates to a method for mounting a safety device and
for mounting the safety device on a syringe body.
Until now, safety devices for avoiding stab wounds have been known
in the art, which are mounted so as to surround the entire syringe
once the syringes have been filled, for example by a supplier,
under cleanroom conditions in a syringe nest or the like.
However, these safety devices increase the dimensions, in terms of
both the sheer size and the weight of the syringe to be used, so
that syringes having safety devices of this type are considerably
more difficult to handle. Furthermore, the costs are also increased
as a result of the greater amount of material used, as is the
production time for a syringe comprising a safety device, since the
safety device has to be assembled on the syringe in several
steps.
Furthermore, such a structure of the safety device does not make it
possible to mount the syringe in a syringe nest together with the
safety device and to fill it therein, since the syringe nest
corresponds to a DIN standard and therefore has a standardised
size. Therefore, the syringe first has to be filled before it can
be provided with the safety device. This of course also runs the
risk of a person injecting themselves with a medicinal product that
has been poured into the syringe.
Furthermore, subsequently attaching said safety device is
disadvantageous in that the syringe that has already been filled
can be damaged when mounting the safety device on the syringe, and
is therefore unusable. This occurs in particular when the syringe
is made of glass or another fragile material. If the syringe is
damaged, the medicinal product contained therein is no longer
useable either, which may lead to increased production costs.
The problem addressed by the present application is therefore that
of providing a method for mounting a safety device so that the
safety device can be mounted on the syringe body before the syringe
body is filled, in particular so that said safety device can be
mounted on the syringe body in a single step.
This problem addressed is solved by a method for mounting a safety
device and for mounting the safety device on a syringe body before
it is filled, comprising the steps of: providing a sleeve, a spring
element and a mounting element; inserting the spring element into
the interior of the sleeve in a mounting direction; inserting the
mounting element into the interior of the sleeve along the mounting
direction; obtaining the safety device; and mounting the safety
device on the syringe body before the syringe body is filled by
connecting the mounting element to the syringe body.
According to the invention, as in the present case, the safety
device is therefore first assembled from a plurality of individual
parts, specifically the sleeve, the spring element and the mounting
element, and then mounted on the syringe body in a single step as a
unit, in this case by connecting the mounting element to the
syringe body.
In this case, the mounting direction extends from a proximal end of
the sleeve towards a distal end of the sleeve. The spring element
and the mounting element are therefore inserted at the proximal end
of the sleeve and pushed towards the distal end, a bearing region
preferably being arranged inside the sleeve, to which region at
least the spring element is operatively connected by introducing
said spring element into the interior of the sleeve, said element
thus resting against the bearing region.
In a similar manner to the spring element, the mounting element is
inserted into the interior of the sleeve. In this case, the
mounting element can preferably be connected to the sleeve so that
the spring element is held in the sleeve by the bearing region on
one side and by the mounting element on the other side. The spring
element is therefore secured such that it cannot fall out of the
sleeve.
If a user of the syringe now moves the syringe body relative to the
safety device, the spring element counteracts said movement and, if
the relative movement is suppressed, would move the syringe body
back again relative to the safety device.
The spring element can therefore ensure that the needle is securely
moved back into the safety device, preferably automatically, after
the syringe has been used. In this case, the spring element can
have various designs. The spring element is preferably a spiral
spring.
According to a preferred embodiment, the mounting element is
connected to the syringe body by placing the mounting element on
the syringe body.
According to a further preferred embodiment, the mounting element
is clipped onto the syringe body, thus ensuring especially simple
and secure mounting of the safety device on the syringe body.
For the mounting process, the mounting element preferably comprises
a mounting opening, in which one or more latching elements may be
arranged in order to clip the mounting element, and thus the safety
device, onto said syringe body.
According to a preferred embodiment, the mounting element is
connected to the sleeve by means of at least one guide pin, the
guide pin advantageously being arranged on the mounting
element.
In this case, the sleeve particularly advantageously comprises one
or more recesses that form a guide track, the guide pin preferably
being inserted into the recess or the guide track and the mounting
element therefore being connected to the sleeve. When the syringe
body is moved relative to the safety device, the guide pin can be
guided by the guide track. For this purpose, it is advantageous for
the mounting element to be able to move radially, i.e. to be able
to rotate about an axis of the syringe body, but unable to move in
the axial direction. This is achieved by clipping the mounting
element onto the syringe body, for example, as described above.
The mounting element can particularly advantageously be inserted
into the sleeve if said mounting element comprises sloping edges
and/or cut-outs in which the guide pin is guided. The sleeve
advantageously comprises a guide track in the form of a recess, in
which the guide pin is introduced and therefore connects the sleeve
and the mounting element to one another. The sloping edge and/or
cut-out is therefore suitable for inserting the guide pin of the
mounting element into the interior of the sleeve in a guided
manner, thus making it easier and quicker to mount the safety
device.
The safety device can be made even safer if an assembly comprising
a cap and a needle guard is provided in addition to the sleeve, the
spring element and the mounting element. This assembly allows the
piercing element, for example a needle, to be guarded more
effectively, in particular before the syringe is used for an
injection. The assembly can advantageously be removed from the
sleeve before the syringe is used.
According to a preferred embodiment, the assembly is connected to
the sleeve by pushing the cap onto the sleeve counter to the
mounting device, thus ensuring particularly simple and rapid
mounting of the assembly on the sleeve.
The sleeve advantageously comprises recesses, which are
complementary to the cap of the assembly so that a non-positive
connection can thereby already be established by pushing to the cap
onto the sleeve.
According to a further preferred embodiment, the syringe body
together with the safety device mounted thereon is sterilised.
Therefore, by mounting the safety device on the syringe body in
advance, the entire arrangement can be sterilised in one step, as a
result of which there is no need for several sterilisation steps,
as is the case in the prior art as a result of subsequently
mounting the safety device, and these steps can be omitted, thus
reducing the production speed for a syringe and the system
complexity.
According to another preferred embodiment, the syringe body
together with the safety device mounted thereon is mounted in a
syringe nest. The syringe nest comprising the syringe body together
with the safety device is preferably mounted in a trough so that
the syringe nest can be transported securely, for example to a
company that fills the syringes. In this case, it is also possible
to seal the trough comprising the syringe nest and syringe,
preferably under cleanroom conditions, by means of a cover, for
example a film.
Additional advantageous embodiments can be found in the dependent
claims.
Additional aims, advantages and expediencies of the present
invention can be found in the following description in conjunction
with the drawings, in which:
FIG. 1 shows a detail of the syringe body;
FIG. 2A is a perspective view of the sleeve from the front;
FIG. 2B is a perspective view of the sleeve from behind;
FIG. 2C is a perspective view of the cap;
FIG. 2D shows the cap being mounted onto the sleeve;
FIG. 3A is a perspective view of the mounting element from
above;
FIG. 3B is a perspective view of the mounting element from
below;
FIG. 4 is a longitudinal section of a syringe body comprising the
safety device mounted thereon;
FIG. 5 shows a syringe nest;
FIG. 6 shows syringes mounted in a syringe nest, comprising a
syringe body and a safety device; and
FIG. 7 is a flow diagram showing the individual method steps
according to one embodiment.
FIG. 1 shows a possible syringe body 1 that forms the basis of the
invention. Commercially available syringe bodies 1 are
substantially cylindrical, as is the syringe body 1 in the present
case, and have a predetermined or predeterminable diameter 13. In
this case, the syringe body 1 also comprises a narrower region 15
at its distal end 14, which is also substantially cylindrical. In
this case, however, the narrower region 15 is in the shape of a
truncated cone, the truncated-cone-shaped narrower region 15 having
a diameter 16 at the cover surface (not shown here), i.e. the
distal end 17 of the narrower region 15, the diameter 16 of the
narrower region 15 being smaller than the diameter 13 of the
syringe body 1.
Furthermore, in this case a needle holder 18 having a piercing
element 19, a needle 19 in this case, is arranged at the distal end
17 of the narrower region 15, said needle holder 18 having a
diameter 20 that is greater than the diameter 16 of the narrower
region 15 but smaller than the diameter 13 of the syringe body 1.
Furthermore, the needle holder 18 is arranged at the distal end 17
of the narrower region 15 such that a transition region 21 is
formed, the transition region 21 forming a region in which the
diameter 16 of the narrower region 15 and the diameter 20 of the
needle holder meet one another and the diameter is thus
intrinsically dramatically changed. The transition region 21 thus
forms a type of projection.
FIG. 2A is a perspective view of a first important component of the
safety device 2, specifically the sleeve 22. As can be seen clearly
from FIG. 2A, the sleeve comprises a recess 24, which forms the
guide track 23 for guiding the guide pin 7 (not shown in this
case). In addition, the sleeve 22 can comprise a recessed region
25, which is delimited by an edge 26. A mirror-image recess 24' is
advantageously arranged opposite the recess 24 in the sleeve 22 and
a mirror-image recessed region 25' is advantageously arranged
opposite the recessed region 25 on said sleeve.
In this case, the recessed region 25 allows a cap 9 (see FIG. 2C)
to be attached in a guided manner in order to increase the safety
of the safety device 2. The cap 9 is at least in operative contact
with and preferably at least non-positively connected to the sleeve
22 by means of the edge 26 of the recessed region 25.
Furthermore, the sleeve 22 comprises an annulus 28 and an annular
region 29 at its distal end 27, which is arranged so as to surround
the annulus 28 when viewed in the radial direction. The cap 9 is
placed on the annulus 28 such that, in addition to being
non-positively connected to the recessed region 25, the cap 9 is
additionally non-positively connected to the sleeve 22.
FIG. 2B once again shows the sleeve 22, but from a different
perspective to that in FIG. 2A. FIG. 2B shows in particular the
proximal end 31 of the sleeve 22, which comprises at least one
slanting portion 32. The number of slanting portions 32 is
preferably equal to the number of guide pins 7, and said portions
are formed on the sleeve 22 so as to be complementary to the guide
pins 7.
The slanting portions 32 constitute a guide for the guide pins 7
when the safety device 2 is assembled, the slanting portions
constituting a depression in the inner wall 34 of the sleeve so
that the wall thickness 35 of the sleeve 22 has been reduced by the
magnitude 36 of the depression 32, making it easier to introduce
the mounting element 5, in particular to introduce the guide pin 7,
into the sleeve 22.
FIG. 2C shows a cap 9, on which a needle guard 10 is likewise
arranged. In this case, the cap 9 comprises a first wing element 39
and a second wing element 40, which are designed to be
complementary to the recessed regions 25. In this case, the
external diameter (not shown here) of the needle guard 10 is
smaller than the internal diameter 41 of the exit opening 30 or of
the sleeve 22, thus ensuring that the needle guard 10 can be
inserted into the sleeve 22.
In the present case, FIG. 2D shows how the cap 9 and the needle
guard 10 are pushed onto the sleeve 22 counter to the mounting
direction 6, which extends from the proximal end 31 of the sleeve
to the distal end 27 along a longitudinal direction of the sleeve
22. Following mounting, an annular region 42 of the cap 9 is
preferably in contact with the annulus 28. However, it is also
conceivable for the annular region 42 to be in contact with the
annular region 29.
FIGS. 3A and 3B show the mounting element 5, by means of which the
sleeve 2 and therefore the safety device 2 can be connected to the
syringe body 1 as a whole, FIG. 3A being a perspective view from
above of the mounting element 5 and FIG. 3B being a perspective
view from below of the mounting element 5.
The mounting element 5 is substantially cylindrical in this case,
having an external diameter 43 and an internal diameter 44.
Reference numeral 45 denotes the distal end of the mounting element
5.
In this case, two guide pins 7 are arranged on a lateral face 46 of
the mounting element 5, which lie on opposite sides of the mounting
element 5. Said guide pins 7 can then be arranged in the guide
track 23 of the sleeve and be operatively connected thereto.
In addition, the mounting element 5 comprises one or more, in this
case two, cut-outs 47 and one or more, in this case three, latching
elements 48, the function of which is outlined below with reference
to FIG. 3B.
In FIG. 3B, reference numeral 49 denotes a proximal end 49 of the
mounting element 5. As can be seen, the latching elements 48 of the
mounting element 5 extend so as to increase in size from the
proximal end 49 towards the distal end 45, i.e. the latching
elements 48 are larger at the distal end 45 than at the proximal
end 49 when viewed in the radial direction.
If, when joining the mounting element 5 and the syringe body 1, in
particular the narrower region 15 thereof, the mounting element 5
is first pushed onto the needle holder 18 by its proximal end 49, a
first half 50 and a second half 51 of the mounting element 5, which
are separated by the cut-outs 47, are moved away from one another
as a result of the difference in thickness in the radial direction
that increases in the axial direction. It is therefore necessary
here for the mounting element 5 to be at least partially
resilient.
If the distal end 45 of the mounting element 5 passes the
transition region 21, the first 50 and the second 51 halves move
towards one another as a result of the resilient design, so that
the mounting element 5 and therefore the safety device 2 are
ultimately clipped onto the syringe body 1.
In order to secure this clip connection, the latching elements 48
comprise securing portions 52 at their distal end 45, which
portions extend in the circumferential direction of an inner circle
53 of the mounting element 5 and are mechanically operatively
connected to the transition region 21.
The safety device 2 comprising the sleeve 2, the mounting element
5, the spring element 4 and optionally the cap 9 can particularly
preferably be mounted in advance and can be connected to the
syringe body 1 as a whole by means of the mounting element 5.
FIG. 4 is a longitudinal section of a syringe body 1 comprising a
safety device 2 mounted thereon.
In addition to the cap 9, the sleeve 22 and the mounting element 5,
the safety device 2 now also features the spring element 4, which
is formed as a spiral spring 4 in this case.
As can clearly be seen, the guide pins 7 are in contact with the
recess 24 or the guide track 23, so that the guide pins 7 are
guided by the guide track 23 when the syringe body 1 is moved
relative to the safety device 2.
The mounting element 5 is clipped together with the narrower region
15 by means of the latching elements 48 and the securing portions
52 thereof, and is connected to the sleeve 22 by means of the guide
pins 7.
The sleeve 22 also comprises an internal bearing region 54 at its
distal end 27, which can be operatively connected to the spring
element 4. The spring element 4 is therefore held in the sleeve 22
by the bearing region 54 on one side and by the mounting element 5
on the other side, and is therefore secured against falling
out.
The safety device 2 is dimensioned such that the sleeve 22 has an
internal diameter 55 that is greater than the diameter 13 of the
syringe body 1, and therefore the syringe body 1 can be moved into
the sleeve 22 when it is moved forwards in the longitudinal
direction L, the movement direction being shown by an arrow L,
relative to the safety device 2. At the same time, the external
diameter 56 of the sleeve 22 or of the safety device 2 is selected
so as to correspond to no greater than a maximum diameter 57 of a
retaining apparatus 58, attached to the proximal end 59 of the
syringe body 1, for retaining and securely positioning the syringe.
The purpose of this size restriction is explained in more detail
with reference to FIGS. 5 and 6.
FIG. 5 shows a syringe nest, as already known in the art,
comprising a base plate 60, on which there are arranged hollow
cylinders 61, i.e. in particular openings 61, in which the syringes
can be mounted. In this case, the base plate 60 is used to fasten
the syringe nest in a trough 12 (not shown in this case).
For this purpose, FIG. 6 shows a detail of a longitudinal section
of a syringe nest 11 comprising syringes mounted therein, the
syringes comprising a syringe body 1 and a safety device 2. In this
case, the syringe body 1 has been mounted in the syringe nest
together with the safety device 2. In order to be able to mount a
syringe in the syringe nest 11, the diameter 57 of the retaining
apparatus 58 is selected to be greater than the diameter 62 of an
opening 61. In order to be able to mount the syringe body 1
together with the safety device 2 in an opening 61, the external
diameter 56 of the sleeve 22 and the external diameter 56 of the
safety device 2 therefore have to be selected to be smaller than
the diameter 57 of the retaining apparatus 58. It is therefore
possible to already mount the syringe in the syringe nest together
with the safety device 2, and to sterilise and fill it therein.
The syringe nest 11 comprising the syringe body 1, the syringe nest
11 being mounted in the trough 12, can then be sealed and/or closed
by means of a cover, in particular a film and/or a membrane. The
film is, for example, made of plastics material and the membrane is
a Tyvek film. Once the trough 12 has been sealed and/or closed, the
arrangement in the present case is sterilised.
FIG. 7 depicts a method sequence according to a particularly
preferred embodiment.
In a first step, step S.1, the respective elements, the sleeve 3,
the spring element 4, the mounting element 5 and the assembly 8
comprising the cap 9 and the needle guard 10 are provided. These
elements are preferably prefabricated components, which are
mass-produced.
In step S.2, the spring element 4 is inserted into the interior of
the sleeve 3 and is secured against falling out by the mounting
element 5 being inserted into the interior of the sleeve 3 in step
S.3.
In a subsequent step, step S.4, onto the sleeve 3 an assembly 8, in
particular the cap 9, is pushed onto the sleeve 3 so that the
safety device 2 is mounted in advance and obtained in step S.5.
The safety device 2 obtained is mounted on the syringe body 1 in a
single step in step S.6 by the safety device 2 being pushed onto
the distal end of the syringe body 1 and the mounting element 5
therefore being connected to the syringe body 1.
Once the safety device 2 has been mounted on the syringe body 1,
the entire arrangement can be mounted in a syringe nest 11 and a
trough 12 in step S.7, and in step S.8 the trough 12 can be sealed,
for example by means of a protective film and/or a membrane,
preferably a Tyvek film.
In a subsequent step, step S.9, the arrangement consisting of the
syringe body 1 comprising the safety device 2 and the trough 12
comprising the syringe nest 11 is sterilised, preferably under
cleanroom conditions.
In a final step, step S.10, the film is preferably removed again so
that the syringe body 1 can be filled. In a subsequent step (not
shown), the syringe bodies 1 that have been filled are provided
with stoppers or the like and thus sealed and then placed in
commercially available packaging.
All of the features disclosed in the application documents are
claimed to be essential to the invention provided that they are
novel over the prior art, either on their own or in combination
with one another.
